1'0 all whom it may concern:

Be it known that I, CHARLES W. OURTIs, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Cooking- Stoves and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, andto the reference-numerals. marked thereon.

My present invention relates to improvements in stoves, and it has forits object to provide a broiler attachm nt adapted to be applied theretoin such a manner that it may be moved into any desired position andautomatically held there by an improved form of latch, which latter maybe released auto matically to permit the return of said at-- tachment toits normal or original position.

To these and other ends, my invention consists in certain combinationsand arrangements of parts to be hereinafter more fully described, thefeatures of novelty being pointed out in the claims hereunto annexed.

In the drawings: Figure 1 is a fragmentary plan View of a stove or othersuitable device embodying my invention. Fig. 2 is a sec tional view onthe line 2-2 Fig. 1, showing the parts in their raised positions. Fig. 3is a similar View on the line 33 Fig. 1, and Fig. 1 is a view similar toFig. 3, showing the relation of the parts while the cover is beinglowered.

In these views, the same numerals of reference designate similar parts.

In order that my said invention may be more fully understood, referencewill be had to the herein shown embodiment thereof, wherein 1 designatesa cover having pivot projections 2, 2 arranged thereon to bear upon thestove top 3 to form a hinged joint for said cover. This cover ispreferably arranged to rest upon the flange 4 and to normally cover theaperture 5 formed in the top of the stove preferably above thecombustion chamber in such a manner that the upper surface of the coverwill be flush or will form a continuous surface with the top of thestove, and fitted into this cover are the usual lids 66, and the centerpiece 7 e011- necting them, an extension 8 carrying a handle 9 beingprovided to facilitate the elevating and lowering of the cover about theproj jections 2, 2 as centers. At one end of the hinged cover thusformed, is provided an offset lug or projection 10, adapted to rest inthe depression 11 of the stove top when the cover is lowered, anddepending from this projection are the bearing lugs 12-12 carrying thepin 13 from which is pivotally sus pended the link or latch 14, thenormal tendency of which is to assume a substantially vertical position.This link is provided upon one edge with one or more notches or teeth15, adapted to engage a relatively fixed cover supporting projection 16preferably carried upon the under side of the stove top, and at thelower portion of said link is provided a curved oil'set portion 17arranged to ride upon the curved surface of the relatively fixed lug 18as it approaches its upper limit of motion, and somewhat offset fromthis lug 18 in a direction laterally of the plane of movement of thecover is provided a slot 19 formed in the stove cover to permit the freepassage of said link therethrough at one side of and thus clear of thesupporting projection for a purpose of permitting lowering or closingmovement of the cover, and as the latch is suspended freely and isdisengaged from the supporting projection when the cover is in closedposition, the latch will automatically swing into position in readinessto move into engagement with the projection on the nextlifting oropening movement of the cover.

The utility of an appliance of this character will be readily apparentto those familiar with the uses to which devices of this class maybeapplied. IVhen the cover is in its normally lowered position, the top ofthe stove has a substantially continuous upper surface, capable of beingutilized for all the purposes of an ordinary stove; but when it isdesirable to utilize the services of a broiler, the cover is lifted upapproximately into the position shown in Fig. 2, and as the cover islifted, the link or latch 14 will ride at one edge upon the projection16, and as the con ter of gravity thereof is carried over and beyondsaid projection toward the pivot due to the relative position of thesupporting pin 13, the notches 15 thereon will automatically drop overthe said projection, to retain the hinged cover at any desired height topermit the introduction of the necessary culinary appliances beneath it.When it is desirable to lower the cover, it is slightly raised until thecurved offset portion 17 of the link rides over the lug 18 to such anextent as to move the link out of line with the projection 16 and todrop by gravity into the slot to permit it 19, which extends back farenough to allow the latch to be freely lowered after its teeth havebecome disengaged from the projection 16, after which it will swing toits normal position. To insure the free and proper operation of the linkin lowering, the arm thereof may be provided with the curved portion 20so arranged as to permit the link to retain substantially a verticalposition while in the slot 19 and to render it possible to locate theoperating parts in close proximity to the side or other parts of thestove. Thus it'will be obvious that I have produced a hinged coverprovided with a latch that will be automatically operated by gravity toretain the cover in the position to which it has been will automaticallyrelease itself when said cover has been elevated slightly beyond itsupper limit of adjustment-allowing said cover to be freely lowered,until it again assumes its normal position upon the flange 4 of theaperture 5, at which time, the latch will have automatically swung intoa position with its notched or toothed edge opposite the projection 16.

An appliance of this character is comparatively inexpensive to fit tostoves, and in operation is particularly useful as a broiler, as thegravity actuated latch enables the device to be manipulated withfacility.

I claim as my invention:

1. The combination with a stove top, a cover pivotally mounted thereon,and a cover-supporting projection onthe stove top having a slot orpassage at one side thereof, of a latch freely suspended on the cover ona pivot so located as to move over said projection and toward the pivotof the cover during the opening movement of the latter to carry thelatch into cooperative relation with the adapted, and that saidprojection, and means for swinging the latch out of alinementwith saidprojection and into a position to enter said passage at the side thereofto permit closingmovement of'the cover.

2. The combination with a stove, and a cover mounted in pivotal relationtherewith, of a toothed latch pivoted to swing in the 1 plane ofmovementof the cover, and having a laterally offset portion thereon, of aprojection arranged on the stove at a point between the pivot of thecover and the latch, the latter being held in cooperative relation withthe projection by gravity as the cover swings in one direction on itspivot, a cam being provided on said projection to cooperate with theoffset portion of the 'latchto automatically disengage jection by acontinued movement of the cover, and a slot being provided adjacent tothe projection to receive and guide the latch after the latter hasdisengaged from the projection.

3. The combination with a stove top, a cover pivotally mounted thereon,and a cover-supporting projection formed on the stove top and having aslot arranged at one side thereof, andextending toward the pivot of'thecover, of a latch on the cover on a pivot so located as to move over thesupporting projection and toward the pivot of the cover during openingmovement of the latter to carry the latch into cooperative relation withthe projection, and a laterally offset portion on the latch serving tomove the latter out of alinement with said projection and into aposition to enter said slot at one side of the projection to permitclosing movement of the cover.

i. The combination with a stove top having an opening therein and a slotleading from said opening, and a cover-supporting projection formed atone side of said opening and adjacent to the said slot, of a coverpivotally mounted on the stove top, a latch freely suspended on thecover by a pivot arranged at'a point to freely suspend the latch in saidopening opposite to the supporting projection when the cover is closed,and arranged to carry the latch into engagement with said projectionwhen the cover is opened on its pivot, said latch having a cam portionarranged to engage a portion of the stove top to move the latchlaterally out of alinement with the projection and into a position toenter said slot, to permit closing movement of the cover.
